Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed February 11, 1920. Serial No. 357,805.

T 0 all w ham it may concern Be it known that I, CHARLES RIDSDALE, a citizen of the United States, residing at the city of Guelph, in the county of Wellin ton and Province of Ontario, Dominion of anada, have invented a new or Improved Bearing, of which the following is a specification.

The object of my invention is a reinforced Babbitt bearing that can be made on the spot with the usual appliances and will fit snugly to the shaft with a tough strong wearing surface.

It consists of a Babbitt metal bearing in which is embedded copper wire of square or other suitable section that shall lie closely against the revolving shaft, thus forming a strong tough wearing surface of any required degree of hardness held firmly in place by the Babbitt metal filling or backing.

I illustrate my invention by the accompanying drawings in which:

Figure I. is a view of the angular hard metal wire forming the wearing surface of my new or improved bearing.

Fig. II. is a view of a section of the same bent into longitudinal loops in a semi-circular form, suitablefor half of a split bear- Tig. III. is a view of a similar section bent into transverse loops for the same purpose.

Fig. IV. is a top view of Fig. III and Fig. V. is a similar view of Fig. II.

Fig. VI. shows the ends of the longitudinal loops as shown in Fig. II, bent outwardly so as to form a flanged bearing.

Fig. VII. is a perspective view of a section of a completed bearing showing the embedded wire, which in this case has been spirally wound around the shaft.

Similar letters of reference indicate similar parts in all the drawings.

In Fig. I the wire is shown in staggered or zigzag loops or convolutions A forming a flat wire grid which may be of any length and coiled for shipment.

These grids may be of any width to suit the shafts'and sections may be cut off of any number of loops to suit the work in hand.

Fig. II. shows a four loop section of the wire bent so that the loops shall lie longitudinally along the shaft, while in Fig. III. a similar section is bent so that the loops lie transversely partly encircling the shaft, in either case formingtheinner surface of part of a split bearing.

In Fig. VI. the ends of the longitudinal loops are bent outward so as to form the flange of a flanged bearing.

In cases where the bearing can be inserted over the end of a shaft the wire is wound tightly around the end of the shaft.

The wire may be of copper or of any other suitable material and while preferably square may be of any suitable flat sided angular section provided its Wearing surface can lie flat against the revolving shaft.

In operation a suitable section of the convoluted wire is cut off the coil and bent into shape. It is then inserted into the boxing and held in position close against the shaft by means of fine wire or any other suitable device, and the boxing is then filled with liquid Babbitt metal B, Fig. VII. which may be of any suitable easily melted material and when cold will then form a solid tight bearing.

The wire may be tinned to facilitate the adhesion thereto of the Babbitt metal.

The convolutions of wire may be of any suitable distance apart and the wire may be drawn to shape or stamped out of sheet metal.

I claim 1. Longitudinally formed loops of copper or other suitable bearing metal wire of angular section convoluted upon itself; embedded in the inner side of a soft metal bearing so as to form a solid, strong tough bearing with a reinforced inner surface.

2. Transversely formed loops of copper or other suitable bearing metal wire of angular section convoluted upon itself; embedded in the inner side of a soft metal bearing so as to form a solid, strong tough bearing with a reinforced inner surface.

3. A new or improved bearing composed of annular coils of copper or other suitable bearing metal wire of angular section with flat faces backed with Babbitt metal.

4.. A new or improved flanged bearing composed of core or skeleton of flat sided angular wire convoluted upon itself into longitudinally formed loops, one end of said loops bent outwardly at suitable angles so as to form a reinforced flange with a back ing of Babbitt metal.
